CARL KALLENBACH, OF

SYKESVILLE, MARYLAND BOTTLE-WASHING MACHINE Application filed April 2,

The present invention relates to a bottle washing machine, designed to clean bottles, such as household bottles of any type in cluding milk bottles and preserving jars the object being to provide a cheap structure adapted to be operated in two positions at right angles to each other at high speed to effectively cleanse bottles. The invention is designed to cleanse the bottles internally or externally and to remove adherent insoluble matter and particularly rust stains from metallic caps recently employed in bottles developed from close contact of the metallic cap employed to effect a seal.

In carrying out my invention I provide a skeleton standard to form a perfectly aligned series of shafts operated by gearing and a reversible yoke carrying clamping means by which the standard may be mounted to turn the cleaning brush on a horizontal aXis or on a vertical axis by transference of a double clamp yoke.

In carrying out my invention I provide a hand or motor operated drive gear, having internal teeth of a relatively large diameter to a companion geared shaft of relatively small diameter to effect a peripheral speed of 1 to 8 on which shaft I mount a gear of larger diameter to engage a pinion on a spindle carrying expansion chuck to engage a flexible shaft carrying a brush. By these means I effect a high speed of rotary movement on the brush spindle well adapted for removal of dried or encrusted organic matter which must be cleansed from the bottles both internally and externally before rendering them suitable for further use.

The several features of my invention will be more fully hereinafter described and will be specifically indicated in the claim as defined in this specification.

In the accompanying drawings illustrating my invention Figure 1 is an elevation of the machine embodying my improvement.

Figure 2 is a median vertical sectional view.

Referring in detail to the drawings 1 represents a skeleton rectangular standard having two parallel supports for a plurality 1828i Serial No; 2683668".

of shafts 2, 3 4, the shafts having end flanges or washers and bein spaced from the several gears by spacing sleeves 5- each of which is provided with a small hole or oil duct 6. A bushing 7 bears against gear 8 tohold its internally toothed rim in gear with a pinion 11 onshaft 2. v I

The drive gears are held in adjusted relation by the nut 7 A handle 9 permits rotary movement to be imparted to the drive gear, which may also be provided with a groove 10 for application of a belt driven by a motor, not shown. A pair of spur gears 12 and 13 impart the necessary speed to the driven spindle it onwhich'is-mounted an expansible chuck 15 to accommodate a flexible wire: shaft or shank 16 carrying a brush 17. The standard 1' is provided with two bolt holes in angular relation at the bottom to accommodate a set screw 19 or 19 by which may be clamped a perforated yoke 18, carrying a thumb screw 20, having a flat clamp disc 21 within the yoke. By this means the yoke 18 may be applied in either of the positions illustrated in Figure l to facilitate the imparting of rapid speed to the brush shaft 16 ona horizontal axis. The necks of bottles and other vessels to be cleaned may then be fed toward the brush head 17 and after receiving same within the confines thereof may be slightly turned in a direction opposite to that pursued by the revolving brush head to facilitate the loosening of encrusted matter from the inside of the bottle.

A similar operation of the brush on the outside of the bottle will loosen any grime that may have collected upon the outside of the bottle After such operation the yoke 18 is detached from the vertical side of the standard 1 and transferred to the bottom hole and clamped to a tank thus driving the spindle in a vertical plane and surrounding it in a vessel containing water. The cleansing operation may be carried on with the bottle filled with liquid or carrying any desired cleanser such as soap to further remove any organic matter or to rinse the bottle inter- .nally and externally. Following such operation the bottles are rendered perfectly sanitary for further use.

It will be apparent that only one of the yokes may be used and transferred to the position of Figure 1 or if transferred to the right angled position may be clamped on a vertical wall such as a sink and will still be horizontal. This adjustable yoke makes the tool valuable as a universal one so to speak for either horizontal or vertical cleaning.

Having thus described my invention what I claim as new is:

-A bottle washing machine comprising a substantially rectangular skeleton standard having parallel posts and apertures arranged at right angles to each other, a pair of gear shafts mounted for cooperative use upon and between said posts, a drive gear mounted upon one of the shafts having an internally tooth faced rim, a spur gear arranged upon one end of the other shaft and cooperatively associated with said rim, a spindle shaft also mounted upon the posts and between the first mentioned shafts, spur gears carried upon the adjacent ends of the second mentioned shaft and spindle shaft and meshingly engaged to impart driving connection to the spindle, a chuck for the spindle shaft, a shank carried by the chuck having a brush head, and a clamping yoke including a shank detachably secured within one of said apertures to dispose said brush head vertically or horizontally.

In testimony whereof I aflix my signature CARL KALLENBACH;
